// Note that the implementation here is in itself racy, but we pretend it does
// not matter because we want this useful in release builds without having to
// pay the cost of using atomics. A race hitting the race checker is likely to
// cause access_count_ to diverge from zero and therefore cause the ThreadRef
// comparison to fail, signaling a race, although it may not be in the exact
// spot where a race *first* appeared in the code we're trying to protect. There
// is also a chance that an actual race is missed, however the probability of
// that has been considered small enough to be an acceptable trade off.
